Lysates were clarified from sonicated nuclei and histone-DNA complexes were isolated with antibody. Libraries were prepared according to Illumina's instructions accompanying NEBNext® Ultra™ II DNA Library Prep Kit for Illumina® (E7546S, NEB). ChIP-Seq with Drosophila spike-in chromatin (Cat. 53083, Active Motif) and Drosophila -specific histone variant, H2Av (Cat. 61686, Active Motif) were added to each sample prior IP for normalization.
